Unfortunately, there's not simple formula to identifying all of the factors of a number and it can be a tedious process when trying to identify the divisors of larger numbers. To find the factor combinations of the number 411,351,515, it is easier to work with a table - it's called factoring from the outside in.
We start by creating a table and writing 1 on the left side and then the number we're trying to find the factors for on the right side in a table. Then, below that, write the numbers as a negative as well.
| 1 | 411,351,515 | |
| -1 | -411,351,515 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 411,351,515.
Example:
1 x 411,351,515 = 411,351,515
and
-1 x -411,351,515 = 411,351,515
Notice both answers equal 411,351,515
With that explanation out of the way, let's continue. Next, we take the number 411,351,515 and divide it by 2:
411,351,515 ÷ 2 = 205,675,757.5
If the quotient is a whole number, then 2 and 205,675,757.5 are factors. In this case, the quotient is not a whole number. Don't write anything down and try the next divisor.
Here is what our table should look like at this step:
| 1 | 411,351,515 | |
| -1 | -411,351,515 |
Now, we try dividing 411,351,515 by 3:
411,351,515 ÷ 3 = 137,117,171.6667
If the quotient is a whole number, then 3 and 137,117,171.6667 are factors. In this case, the quotient is not a whole number. Don't write anything down and try the next divisor.
Here is what our table should look like at this step:
| 1 | 411,351,515 | |
| -1 | -411,351,515 |
Let's try dividing by 4:
411,351,515 ÷ 4 = 102,837,878.75
If the quotient is a whole number, then 4 and 102,837,878.75 are factors. In this case, the quotient is not a whole number. Don't write anything down and try the next divisor.
Here is what our table should look like at this step:
| 1 | 411,351,515 | |
| -1 | 411,351,515 |
If you did it right, you will end up with this table:
| 1 | 5 | 29 | 145 | 193 | 965 | 5,597 | 14,699 | 27,985 | 73,495 | 426,271 | 2,131,355 | 2,836,907 | 14,184,535 | 82,270,303 | 411,351,515 |
| -1 | -5 | -29 | -145 | -193 | -965 | -5,597 | -14,699 | -27,985 | -73,495 | -426,271 | -2,131,355 | -2,836,907 | -14,184,535 | -82,270,303 | -411,351,515 |
